The short answer: no. Apophis will not hit Earth in 2029, and NASA's current calculations rule out an impact for at least the next century. But the longer answer is more interesting, because Apophis was once one of the most feared asteroids ever found.
Apophis was discovered in June 2004. Within months, early orbit calculations, based on only a few days of observations, showed a small but real chance of an impact on April 13, 2029. At one point it reached level 4 on the Torino Scale, the highest rating any asteroid has received. Level 4 means "close encounter with a 1% or greater chance of a collision capable of regional devastation."
That number was not a prediction. It was a measure of uncertainty. When an asteroid is first found, astronomers know its path only roughly. As more observations come in, the uncertainty shrinks and risks almost always drop to zero.
The old worry was about a "gravitational keyhole": a tiny region of space that Apophis could pass through in 2029. If it did, Earth's gravity would bend its path just enough to set up a collision on a later pass. Measurements show Apophis will miss the keyhole, so that scenario is off the table.
Apophis is affected by the Yarkovsky effect, a very slight thrust caused by the way a rotating asteroid absorbs sunlight and radiates heat. It is tiny, but it adds up over years. Scientists include it in their models, and the 2029 flyby will give them a rare chance to measure it more precisely.
The flyby itself will also change Apophis. Earth's gravity will alter its orbit and may change its spin and shape. After 2029, astronomers will re-calculate its path, but nothing suggests the outcome will bring a threat.
Apophis will pass about 32,000 km above Earth's surface. That is close for its size, but far from a collision. It will not cause earthquakes, tides or any noticeable effect on Earth. Learn more in our complete Apophis guide.
Apophis is a case study in how planetary defense works: find the object, track it, and let the numbers settle. The scary headlines of 2004 turned into a safe, spectacular flyby, and a great scientific opportunity. See also: how humanity learned to move an asteroid.
